Putty Pads for Soundproofing Electrical Boxes and Wall Penetrations
Custom Acoustic Panels Designed to Absorb Noise and Enhance Sound Quality
Putty pads are flexible, fire-rated acoustic sealants designed to maintain the soundproofing integrity of walls and ceilings where penetrations occur — especially around electrical outlets, light switches, and data boxes. Made from intumescent material, these pads expand under heat and help block both sound and fire from passing through small gaps. Easy to install and mold by hand, putty pads are essential for completing a high-STC (Sound Transmission Class) wall system and are commonly used in residential and commercial soundproofing projects.
Why Use Putty Pads in Soundproofing Projects?
Even a single unsealed outlet box can reduce the effectiveness of a soundproof wall. Putty pads are a fast and effective solution to prevent noise leaks and ensure your walls maintain their designed STC rating. By sealing outlet boxes, putty pads not only block airborne noise but also act as a firestop, helping meet building code requirements.
Easy, Tool-Free Installation
Installing putty pads is quick and easy. Simply peel off the protective backing and press the pad firmly around the electrical box, overlapping seams where necessary. Pads can be cut to size with a utility knife or scissors and reshaped as needed.
Pro Tip: Install before drywall to ensure a perfect fit and full coverage.
Once installed, drywall can be placed directly over the box without issue — no curing time, no mess, and no compromise in sound or fire performance.
